In transport, however, the plastic improves the aerodynamics of a cardecreasing the Cd (drag coefficients), it reduces the weight, thus resulting inlower fuel consumption (on average today 4% less than a full metal car) and thereduction of pollutant emissions. Plastic istherefore now regarded as a must for the new ecology, particularly whenrecycled. A lot of companies have built all-plastic-objects with no attempt tomimic natural materials, claiming one's "plastic" nature linked toyoung people values of lightness, play, color and freshness. Another veryimportant area is that of packaging, a recent study conducted in Germany haveshown that without plastic packaging the weight of the product plus the onepackaging will increase by 291%, the energy used to produce the same 108% andvolume of waste by 158%. The car is the sector where there is thehighest level of use of recycled material. In terms ofmechanical recycling, the plastics used in this area is usually clean anduniform, and through a closed loop processing allow to obtain a high qualitymaterial which has a large market. And thebig numbers Brass Door Stop factory involve the killing of prices, without detracting from the quality. The road to eco-friendly materials is now required and it is alsoknown as a leading route of development for this market. The produce of polyethylene, one of the cheapest plastics, forexample allows to create insulation for electrical cables, films foragriculture, bags and plastic bags, containers of various types, piping, innerlayer of aseptic liquid and food containers and many others.Plastic is in factnow central to the current industrial system, there are a lot of plastic typesand suitable for many uses, but just thinking to replace it seems entirelyimplausible. In furniture market, dominated by anhandicrafts industry, plastic allows for a real industrial production.The plasticmaterial is considered a pure, practical, flexible and technologicallyadvanced. In the food, the use of plastic packaging can containup to 2% the volume of goods that would otherwise reach up to 50%. Plastics are alsoextremely flexible and are perfect to indulge the creativity, as happened inthe '70s with the development of design. In construction, insulation using plasticfor every kilo of plastic has an annual saving of 75 kilos of fuel for heating. Another veryimportant field is the economic one.4pt 0cm 5.
